Google earlier this week made its fifth acquisition for the month of August. The target this time was SocialDeck, which develops social gaming technology for mobile devices and social networks. The company's games include PetHero, Shake&Spell, and ColorConnect, and it also develops a social-networking platform called Spark that connects players across devices.

SocialDeck announced news of the acquisition on its Web site, with very few details.

"We started this company with the goal of connecting friends through games on all kinds of exciting new mobile devices," reads SocialDeck's Web site. "We've been amazed and humbled by all of the stories our customers have shared with us."

The company was founded in 2008 and has a number of titles for the iPhone and BlackBerry mobile devices, as well as for Facebook. The company received its first round of funding from BlackBerry Partners Fund in 2009.  In addition to developing games, it creates technology for viral content discovery, distribution, and monetization, according to the company's Web site.

The acquisition fuels speculation that Google is looking to get into the social networking arena with its own offering.
